<p>PURPOSE:To reduce and simplify the program work by discriminating a straight line or an arc in accordance with working information of a work drawing and designating a straight line or an arc on a selection picture. CONSTITUTION:In case of generating NC data of shape parts which consist of the combination of straight lines and arcs, the selection picture on which a straight line or an arc is designated, a straight line input picture on which physical properties of the straight line and the feed speed are inputted only with numerical values in accordance with a guide picture, and an arc input picture on which arc information is inputted similarly to the straight line are provided, and these three pictures are used to continuously input numerical values with respect to the locus from the start point to the end point of the work drawing of shape parts. If start points, end points, radiuses, etc., of respective straight lines and arcs are distinct, these numerical values are used as working information; but if they are indistinct and a pattern cannot be unequivocally determined, that is, if the pattern is obtained in accordance with relations to the following pattern or indistinct round numbers are inputted with respect to intersections or the like between patterns, accurate numerical values are internally operated in accordance with contexts of input to obtain start points, end points, and radiuses of respective straight lines and arcs.</p> |
